Bit A30601 is ON when the PC is not running because an I/O Verification Er-
ror has occurred, and the PC Setup are set so the PC does not run when an
I/O Verification Error occurs. The PC Setup can be changed to enable opera-
tion during I/O Verification Errors. Refer to “Comparison error process” in the
PC Setup.
Bit A30602 is ON when the PC is not running because there is a terminator
missing in the SYSMAC BUS System.
Bit A30603 is ON when the PC is not running because a CPU Bus Unit is
initializing, or a terminator missing in the SYSMAC BUS/2 System.
3-6-18 Peripheral Device Flags
Bits A30608 through A30611 contain a binary code that identifies the type of
Peripheral Device (0: FIT10; 1: FIT20; 2: GPC; 3: Programming Console)
connected to the CPU, the Expansion CPU, or an Expansion I/O Rack.
Bit A30615 is ON when a Peripheral Device is connected to the CPU, the
Expansion CPU, or an Expansion I/O Rack.
Bits A30700 through A30815 are turned ON when a Peripheral Device is
connected to the corresponding Slave Rack, as shown in the following table.
Word Bits
00 to 07 08 to 15
A307 Racks #0 to #7 on Master #0 Racks #0 to #7 on Master #1
A308 Racks #0 to #7 on Master #2 Racks #0 to #7 on Master #3
Word A309 contains the cycle time in ms (in binary) required to service Pe-
ripheral Devices, Host Link, and CPU Bus Units. Refer to
6-2 Cycle Time
for
details.
3-6-19 CPU Bus Unit Service Interval
Words A310 through A325 contain the interval in ms (binary) between CPU Bus
Unit services for Units #0 through #15, respectively. Measuring the service inter-
val can be enabled or disabled in the PC Setup.
3-6-20 Memory Card Flags
The binary number stored in A34300 to A34303 indicates the type of Memory
Card, if any, installed in the Memory Card Drive. (0: None, 1: RAM,
2: EPROM, 3: EEPROM)
Bit A34307 is turned ON when the Memory Card is not formatted or a format-
ting error has occurred.
Bit A34308 is turned ON when an error occurs while writing to the Memory
Card.
Bit A34309 is turned ON when the Memory Card cannot be written to be-
cause the card is write-protected, EPROM, EEPROM, data is beyond the
capacity of the card, or there are too many files.
Bit A34310 is turned ON when the specified file is damaged and cannot be
read.
